How Can I Protect the Exterior of My Home in a Coastal Climate?

Living on Alabama’s Gulf Coast means the exterior of your home has to handle a lot. Heat, intense sun, humidity, heavy rain, wind, and—in areas closer to saltwater—salt in the air can all take a toll on exterior materials over time.

Regular maintenance can help you catch small problems early, protect the materials that make up your home, and extend the life of exterior finishes and components.

Inspect the Exterior Regularly

You don't have to wait until something looks obviously wrong to take a closer look at your home's exterior.

Periodically walk around the house and look at the siding, trim, soffits, fascia, windows, doors, porches, decks, and other exterior surfaces.

Watch for things such as peeling or bubbling paint, cracked or deteriorated caulk, loose materials, staining, soft or damaged wood, rust, or areas where water may be getting in.

Catching a small maintenance issue early is usually much easier than discovering it after moisture has reached materials underneath.

Keep Paint, Caulk, and Sealants in Good Condition

Exterior paint isn't only about appearance. It can also help protect certain building materials from moisture and weather exposure.

Our sun, heat, and humidity can be hard on exterior finishes, so watch for fading, peeling, cracking, or areas where the protective coating has worn away.

Also inspect caulk and sealants around windows, doors, penetrations, and other appropriate areas. If they're cracked, separated, or deteriorating, they may need attention.

Watch for Corrosion

Salt air can accelerate corrosion of some metals, particularly for homes located closer to the water.

Periodically check exterior hardware, fasteners, railings, light fixtures, door hardware, HVAC components, and other exposed metal for signs of deterioration or corrosion.

The amount of exposure varies considerably depending on how close the property is to saltwater and the home's surroundings, so maintenance needs won't be identical for every Gulf Coast property.

Keep Exterior Surfaces Clean

Dirt, pollen, mildew, algae, salt residue, and other buildup can accumulate on siding, porches, decks, railings, and exterior fixtures.

Cleaning these surfaces periodically can help maintain their appearance and make it easier to notice developing problems.

Use cleaning methods appropriate for the particular material. More pressure isn't always better—improper pressure washing can damage siding, paint, wood, seals, and other exterior components.

Pay Attention to Porches, Decks, and Railings

Outdoor living spaces get plenty of exposure to sun, rain, humidity, and moisture.

Periodically inspect decking, stairs, porch floors, railings, posts, and connections for loose components, deterioration, peeling finishes, soft wood, corrosion, or other changes.

Wood surfaces may need periodic cleaning, sealing, staining, or painting depending on the material and exposure. Composite and other materials have their own maintenance recommendations, so follow the manufacturer's guidance when available.

Keep Vegetation From Taking Over the House

Landscaping can grow quickly in our climate.

Keep shrubs, vines, and tree limbs from constantly rubbing against siding, trim, rooflines, or other exterior surfaces. Vegetation that stays pressed against the house can trap moisture and make it harder to inspect the exterior.

Also keep an eye on irrigation systems so sprinklers aren't repeatedly spraying siding, doors, windows, or the foundation unnecessarily.

Check Exterior Components After Severe Weather

After strong winds or severe weather have passed and conditions are safe, walk around the property and look for changes.

Check for loose siding or trim, damaged screens, missing roofing materials visible from the ground, damaged gutters, fallen limbs, or other exterior issues.

You don't need to climb onto the roof yourself. If you suspect damage in an area you can't safely inspect, have an appropriate professional evaluate it.

Choose Exterior Materials With the Climate in Mind

When it's time to replace siding, trim, decking, fasteners, fixtures, doors, windows, or other exterior components, consider how the material performs in our climate.

Products that work well in one environment aren't necessarily ideal everywhere. Exposure to moisture, intense sun, wind, and salt air can affect longevity and maintenance requirements.

Ask contractors or manufacturers about products appropriate for your home's specific location and exposure rather than choosing based on appearance alone.

Keep Records of Exterior Improvements

Save invoices, warranties, product information, permits when applicable, and photographs from major exterior projects.

Knowing when the house was painted, when windows or doors were replaced, what roofing materials were installed, or which products were used on a deck can make future maintenance much easier.

Those records can also be helpful when you eventually sell the home.

Frequently Asked Questions

Does every Gulf Coast home have problems with salt air?
No. Salt exposure varies considerably depending on a home's distance from saltwater, prevailing conditions, and surroundings. Homes very close to the coast may experience more salt-related corrosion than properties farther inland.

How often should I repaint the exterior of my home?
There's no single schedule that works for every house. Paint type, exterior material, preparation, sun exposure, moisture, and other conditions all affect how long a finish lasts. Watch the condition of the paint rather than relying only on a specific number of years.

Should I pressure wash my house every year?
Not necessarily. Exterior surfaces may benefit from periodic cleaning, but the appropriate method and frequency depend on the material and amount of buildup. Excessive pressure can damage some surfaces.

Why is the caulk around my windows important?
Caulk and other properly installed sealants can help prevent water and air from entering certain joints and gaps. Deteriorated caulk can be an early maintenance issue worth addressing before surrounding materials are damaged.

What should I do about rust on exterior metal?
Small amounts of surface corrosion and significant deterioration aren't the same thing. Appropriate treatment depends on the component and material. If corrosion affects a structural, electrical, HVAC, railing, or other important component, have the appropriate professional evaluate it.

Do I need special materials because I live on the Gulf Coast?
Not necessarily for every project, but our climate and a property's particular exposure are worth considering. When replacing exterior components, ask about products and installation methods appropriate for the conditions at your home.
